I'm new to this forum, so Hi!  
My AT&T S5 was delivered today. I've had an S3 for a couple of years. Apparently I can use Smartswitch to transfer everything (?) to my new S5. I'm probably making this harder than it needs to be, but should I start fresh with the new SIM card, or switch my old one over to the new one after the transfer is done?
Any tips?
I didn't realize I was going to need a new charger.
  Other than that, I hope I don't find anything else significant I don't like about it.  And geez, the battery is BIG.  Hopefully the size equates to battery life, as compared to S3's.....
Thanks in advance.
